Roots Blower,Three Roots Blower

Product Features
1.The blower hereof adopts the original curve track and the optimied design to improve the full-adiaatic efficiency as well as the volumetric efficeiency Which makes the capacity vs. Pressure superior.
2.The screen lines adopt the helical construction which used
the method of casing at the suction and discharge sides to be cut to a helical shape. The triangle suction and discharge port formed by a straight line of the rotor top is openedand closed gradually which makes the operation more balanced and the liberation and noise limited.
3. The structure design adopts the design preventing the bearing oil and gear oil from entering the casing which makes it clean without any oil to prevent the air pollution due to the fog oil.
4.Compact Structure.The Special bearing and oil seal has improved the service life, which makes the maintenance management conveniently as well.
5.The blowers and bearing adopt the pressuredistribution structure. There are small spaces between blowers which make them free from each other and keep the blower performance standing and operating continual for ling time
